4.1 Topic+Comment Structure
The basic principle in making Chinese sentences is to follow the “topic+comment” structure.
“Topic” means the subject matter you want to talk about, and “comment” is the information you give
about the subject matter. To make a Chinese sentence, you simply first mention the subject matter
you want to talk about, and then say what you have to say about it. For example, you can say 这件
事 zhè jiàn shì (this matter/affair) first as the “topic” and then add “comment”:
这件事 我不清楚。Zhè jiàn shì wǒ bù qīngchǔ. I’m not clear about this matter.
这件事 我很了解。Zhè jiàn shì wǒ hěn liǎojiě. I know this matter well.
这件事 谁都不知道。Zhè jiàn shì shuí dōu bù zhīdào. Nobody knows this matter.
这件事 我不感兴趣。Zhè jiàn shì wǒ bù gǎn xìngqu. I’m not interested in this matter.
这件事 最近社交网站都在谈。Zhè jiàn shì zuìjìn shèjiāo dōu zài tán. Social media are all
talking about this matter these days.
4.2 Ellipsis of Sentence Elements
Chinese speakers may leave out words that are supposed to be understood, and therefore need not
be spoken. Subjects and conjunctions are often omitted. For example, you may translate the English
sentence If you like it, you may buy it, but if you don’t like it, you don’t have to. into the Chinese
sentence 喜欢就买,不喜欢就别买。Xǐhuan jiù mǎi, bù xǐhuan jiù bié mǎi. Compare the
two sentences, and you will find that some English words, such as if, you, it, and but are not
translated.
4.3 Word Classes: Flexibility, No Inflection
Chinese words do not have inflections, i.e. they do not change to indicate grammatical categories.
For example, the verb 做 zuò (to do) is invariably 做 zuò; there is no past form or any other
inflected form of this verb. Neither do Chinese words normally have formal markers of word class.
Consequently, it is rather easy for a word to be used in more than one word class. This relative
flexibility in word classes, however, does not mean that Chinese does not have word classes (see
Section 4.5).
4.4 Measure Words and Particles
Measure words (量词 liàngcí) and particles (助词 zhùcí) are two word classes found in Chinese
but not in English and most other languages.
Measure words are usually required when a noun is modified by a numeral. For example, 两书
liǎng shū is unacceptable; you must use the measure word 本 běn between the numeral and the
noun: 两本书 liǎng běn shū (two books). Furthermore, Chinese nouns require specific measure
words to go with them. For example, the noun 书 shū (book) must be used with the measure word
本 běn. See List 2 Measure Words.
In Chinese grammar, particles are words attached to other words or at the end of a sentence to
indicate grammatical concepts or to express emotions. For example, the particles 了 le, 着 zhe,
过 guo are attached to verbs to indicate, respectively, whether the actions denoted are completed,
in progress or past experiences.
